Background:

The presence of Laemonema verecundum (Jordan & Cra mer, 1897) had not been previously reported at depths less than 666 m.

Goals:

The objective of the research was to study the bathymetric distribution of L. verecundum.

Methods:

In the eastern continental shelf of the Gulf of California, 648 specimens of L. verecundum were collec ted during two experimental research cruises in September 2004 and February 2005.

Results:

Specimens were collected at depths between 165 and 483 m, where temperatures ranged between 9.5 and 19.9° C, and average oxygen concentration was 1.7 mg/l.

Conclusions:

This new record expands the known bathymetric distribution range of this species inhabiting shallow waters in the gulf.
